is a bread-guard.

You will perceive, moreover, that many a dignified word once involved the
same idea as some unassuming or even semi-disreputable word or expression
involves now. Thus there is little or no difference in figure between
understanding a thing and getting on to it; between averting something
(turning it aside) and sidetracking it; between excluding (shutting out)
and closing the door to; between degrading (putting down a step) and
taking down a notch; between accumulating (heaping up) and making one's
pile; between taking umbrage (the shadow) and being thrown in the shade;
between ejaculating and throwing out a remark; between being on a tension
and being highstrung; between being vapid and having lost steam; between
insinuating (winding in) and worming in; between investigating and
tracking; between instigating (goading on or into) and prodding up;
between being incensed (compare _incendiary_) and burning with
indignation; between recanting (unsinging) and singing another tune;
between ruminating (chewing) and smoking in one's pipe. Nor is there much
difference in figure between sarcasm (a tearing of the flesh) and taking
the hide off; between sinister (left-handed) and backhanded; between
preposterous (rear end foremost) and cart before the horse; between salary
(salt-money, an allowance for soldiers) and pin-money; between pedigree
(crane's foot, from the appearance of genealogical diagrams) and crowsfeet
(about the eyes); between either precocious (early cooked), apricot (early
cooked), crude (raw), or recrudescence (raw again) and half-baked. To
ponder is literally to weigh; to apprehend an idea is to take hold of it;
to deviate is to go out of one's way; to congregate is to flock together;
to assail or insult a man is to jump on him; to be precipitate is to go
head foremost; to be recalcitrant is to kick.

Again, you will perceive that many words once had more literal or more
definitely concrete meanings than they have now. To corrode is to gnaw
along with others, to differ is to carry apart, to refuse is to pour back.
Polite is polished, absurd is very deaf, egregious is taken from the
common herd, capricious is leaping about like a goat, cross (disagreeable)
is shaped like a cross, wrong is wrung (or twisted). Crisscross is
Christ's cross, attention is stretching toward, expression is pressed out,
dexterity is right-handedness, circumstances are things standing around,
an innuendo is nodding, a pa
